Sync Samsung data?

I had the Samsung galaxy s9 before and have now got the S20.

Now I wanted to synchronize with Smart twitch, so to speak, transfer the data from one old cell phone to the other.

But after I have transferred the data to my new cell phone, can I delete it on my old cell phone or do the pictures etc. Disappear from both cell phones?

Before deleting you should deactivate the synchronization connection to the new mobile phone or, ideally, delete it.

(WITHOUT GUARANTEE! The devices do not all tick the same)

I recommend backing up all data to an external memory beforehand.
